ELASTIC WEBBING AND METHOD IN WEAVING- THE SAME.

To all whom it may concern Be it known that I, VALDEMAR Kors, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Elastic Webbing and the Methods in Weaving the Same, of which the following is a specification.

My invention relates to elastic Webbing with elastic or in-elastic parts adapted for use for suspenders and other articles of wearing apparel, with the provision of connecting one end of the webbing as desired,

. and the other end at two points in diverging members.

In the webbing of my present invention I produce a strip of elastic webbing parallel sided and for any desired length and at predetermined intervals divide this webbing into two diverging members, which diverging members may be elastic or inelastic, but are preferably in-elastic. These two diverging members may be each one half the width of the elastic member from which they are divided, or the two diverging members may be of any other proportion, the sum of which equals the width of the elastic member from which they are divided, and I prefer to weave the elastic members in alternating sections with the diverging members and duplicated converging members, that is to say, in the weaving of a continuous length the divided members spread apart to a maximum width and come together again into the single parallel sided elastic strip. In the method of weaving this form of webbing, the loom is rigged up with a double shuttle lay and with graduated movable reeds. The parallel sided elastic part of the webbing is woven in the ordinary and well-known manner so that for weaving this part the loom is run as usual for any given piece of elastic webbing, but at predetermined intervals a second shuttle is used, and each of the two shuttles then weaves one of the diverging members. The movable reed continues moving in an upward or downward direction. The reed is formed fan shape, and, consequently, spreads the two divided members gradually apart and when the end of the divided members or their extreme spread position is reached, the reeds gradually move together again and the continued weaving of the divided part converges, until the weav- Specification of Letters Patent.

ing again comes together, after which the strip is woven parallel sided in the ordinary manner as in any piece of elastic webbing until the diverging and converging divided parts are again reached and the parts are repeated. The limit of degree of divergence is only reached when the warp and weft threads no longer form an angle of intersection, but lie parallel to each other, hence the amount of divergence may be made extreme or comparatively slight, at the pleasure of the weaver, and according to the use to which the webbing is to be put.

In the drawings Figure 1 is a plan illustrating the preferred form of webbing of my improvement. Fig. 2 is a plan illustrating a modified form of my improved webbing and Fig. 3 is a plan representing portions of a continuous strip of such webbing.

(4 represents the elastic sections parallel sided and of any desired length, width or thickness.

b 5 represent the divided members integral from one end of the elastic section, according to Fig. l, and integral from both ends of the elastic section, according to the continuous length illustrated in Fig. 3. The divided members I) b diverge. They may be one-half of the width of the elastic section. They may also be of other widths so long as the sum total of the two widths agree with the width of the parallel sided elastic section. These divided and diverging parts may be of any length and the ratio of their divergence may be at any desired angle, and I prefer in the weaving to weave sections a and b 6 continuous so that after weaving the elastic section of the desired length, the divided parts 6 b are woven at the desired angle and width and of the length required. The weave is then continued, but the divided parts are brought gradually closer together and of corresponding length until they come together, and then the parallel sided elastic section is woven again and the weaving operations repeated.

I prefer in weaving the continuous parts to weave the elastic sections of sufficient length to be cut at about the center and the divided members to be out also at about the center, then each piece as severed consists of an elastic section and two divided members suitable for suspenders or other articles de sired.

in-elastic by methods described, illustrated and claimed in other patents or applications for Letters Patent previously filed by me.

In Fig. 2 I have shown an elastic section a and divided members 6 b as made all elastic, consequently without the extra weft threads illustrated and required for the form of my invention shown in Fig. 1.

The divided members are woven by the employment of two shuttles and movable reeds or a reed of fan-like shape. The form of the said reed, however, forms no part of my present invention.

I have shown in Figs. 1 and 2 the severed divided diverging ends I) b as finished by metal or other suitable ends 0 and the webbing provided with button holes (Z.

I am aware that it is not new in this art to weave a parallel sided elastic webbing with parallel divided parts at one end which are finished and made with button holes. In this case, however, the divided ends did not ,diverge,hence when spread they buckled at their union with the main part and would not lie fiat.

I claim as my invention:

1. A length of flat webbing comprising alternate elastic sections of the desired length and width and intermediate divided diverging members or sections formed integral with the elastic sections, and which in the continuous strip diverge and converge.

2. The method herein specified of weaving a flat webbing having an elastic part and integral divided diverging members or parts at one end thereof consisting in weaving the elastic parallel-sided part in the ordinary manner and in weaving the divided diverging members of parts with two shuttles and additional weft-threads and movable fan-shaped reeds substantially set forth.
